RESUMEN
In the literature, midgut volvulus is a well-known surgical complication following gastric bypass surgery that is serious and necessitates an immediate intervention. Here, we report a case of internal herniation that was misdiagnosed twice but eventually managed appropriately. A 27-year-old male with a surgical history of Roux-en-Y gastric bypass came to the emergency department complaining of severe epigastric abdominal pain. Two months earlier, he had a similar pain which was treated with Helicobacter pylori eradication therapy. Despite completing the eradication therapy, the pain reoccurred. Computed tomography angiography showed a filling defect in the superior mesenteric artery that was followed by a diagnostic laparoscopy ending with internal hernia reduction. Physicians should consider internal herniation as a differential diagnosis for every patient with a history of gastric bypass surgery presenting with abdominal pain.
RESUMEN
Introduction: The cyclical changes of hormones during the menstrual cycle are responsible not only for reproductive function but also have other effects on dietary intake and appetite. The current study aimed to investigate the variations of appetite-related hormones (ghrelin and obestatin) during the menstrual cycle and their association with adipokines, estrogen, and BMI. Methods: Fifty-six regularly menstruating female students were grouped into normal weight (BMI ≤24.9; n = 26), and overweight/obese subjects (BMI ≥25; n = 30). Serum ghrelin, obestatin, leptin, adiponectin, and estrogen levels were measured during the early follicular, preovulatory, and luteal phases of the menstrual cycle using the ELISA technique. Results: There were insignificant differences in the levels of serum ghrelin, obestatin, and ghrelin/obestatin ratio across menstrual cycle phases in the whole cohort as well as in each group separately (p > 0.05). Serum ghrelin was significantly less in OW-OB as compared to the NW group (p = 0.005), whereas the average serum obestatin did not show any significant differences between the two groups. No significant correlation was seen between ghrelin and obestatin with the adipokines and estradiol. Conclusion: Significant low level of ghrelin was observed in obese group during the follicular phase. This finding may provide new insights into the altered ghrelin patterns in OW-OB individuals, as a cause or a consequence of obesity and related menstrual disorders.
RESUMEN
Lateral medullary syndrome (LMS), also known as Wallenberg syndrome, is a cerebrovascular event following ischemia of the lateral part of the medulla oblongata. Some of its etiologies include atherosclerotic changes, hypertension, thromboembolism, vertebral artery dissection (VAD), and aneurysm. We present a case of a 45-year-old male with LMS with a gradual onset of atypical symptoms of LMS, which has led to a late diagnosis of our patient. VAD is a commonly recognized cause of stroke in young people and it is a more frequent cause of LMS than posterior inferior cerebellar artery diseases. This case highlights the importance of early identification of signs and symptoms and that appropriate investigation should take place to optimize patient life quality and prognosis.
